FIELD: chemistry.
SUBSTANCE: method of processing underground producing layer involves pumping a water-based liquid thickened by a viscoelastic surfactant into the underground producing layer, pumping into the underground producing layer a microemulsion before, after and/or simultaneously while pumping into the underground producing layer the water-based liquid thickened by a viscoelastic surfactant, where the microemulsion contains: at least one agent for reducing viscosity, containing at least one unsaturated fatty acid, at least one solubility agent, at least one desorption agent and at least one water-wettability agent.
EFFECT: more complete removal of said liquids, removal of residues or deposits left by the said liquids.
